Adjustment procedure 1
(when a color differential meter is used)
1. First adjust [MID-L] tone [G:].
2. Select adjustment point [No.2][G:].
When the background is not [G] monochrome,
press the [MENU SELECT] key on the Remote
control transmitter to change to solid [G]
monochrome.
3. Measure the illumination at adjustment points No.
2, No.3, No.10 and No.11.
The values should be:
No.2 = Y2 [lx]
No.10 = Y10 [lx]
No.3 = Y3 [lx]
No.11 = Y11 [lx]
4. No.2 and No.3 adjustment point have the average
of Y2 and Y3.
Y2 = ( Y2 + Y3 ) / 2 ± 2 [%]
Y3 = ( Y2 + Y3 ) / 2 ± 2 [%]
5. No.10 and No.11 adjustment point have the
average of Y10 and Y11.
Y10 = ( Y10 + Y11 ) / 2 ± 2 [%]
Y11 = ( Y10 + Y11 ) / 2 ± 2 [%]
6. Then adjust [MID-L] tone [R] and [B].
When the background is [G] monochrome, press
the [MENU SELECT] key on the Remote control
transmitter to change to solid white.
7. Measure the color coordinates of adjustment point
[No.1] and make a note of them.
Assume that they are x = x1, y = y1.
Note: When the CL-100 color and color difference
meter is used, the [ ](delta) mode is
convenient. When adjustment point [No.1]
color coordinate has been selected, set the
slide switch on the side to [ ](delta) while
holding down the [F] button on the front
panel. The measurement shown after this
displays the deviation from measurement
point 1.
8. Measure the color coordinates of measurement
point [No.2] and adjust [No.2][R:] and [B:] so that
the coordinates are as follows.
x = x1 ± 0.005 , y = y1 ± 0.010
9. Similarly, measure adjustment points [No.3] to
[No.17] and adjust their color coordinates starting
in order from the small number points.
This completes adjustments required for [MIN].
Note: Since excessive correction may lead to a
correction data overview during internal
calculations, use the following values for
reference.
[No.2] to [No.5] ± 40 or less
[No.6] to [No.9] ± 50 or less
[No.10] to [No.13] ± 70 or less
[No.14] to [No.17] ± 120 or less
10.Then adjust [MIN] tone [G] so that the adjustment
data set two times as much as [MID-L] tone [G].
This completes [G] color adjustments.
11.Then adjust [MIN] tone [R] and [B].
Select [No.2] [B:] and press the [MENU SELECT]
key on the Remote control transmitter to change to
solid white.
12.Measure the color coordinates of adjustment point
[No.1] and make a note of them.
Assume that they are x = x1, y = y1.
13.N o w m e a s u r e t h e c o l o r c o o r d i n a t e s o f
measurement point [No.2] and adjust [No.2][R:]
and [B:] so that the coordinates are as follows.
x = x1 ± 0.005 , y = y1 ± 0.010 (Target)
x = x1 ± 0.020 , y = y1 ± 0.040
14.Similarly, measure adjustment points [No.3] to
[No.17] and adjust their color coordinates starting
in order from the small number points.
This completes [MIN] tone adjustments.
15.Now make similar adjustments for [MID-H] tone.
(Adjust [MID-H] tone [G] so that the adjustment
data set half as many as [MID-L] tone [G].)
16.Now make similar adjustments for [MAX] tone.
(Adjust [MAX] tone [G] so that the adjustment data
set half as many as [MID-L] tone [G].)
